A store manager created this table representing the relationship between the reported days of an outside temperature of over 80º Fahrenheit during a given month, x, and the sales revenue of swimwear, y, rounded to the nearest dollar. Using the linear best-fit model for the data, what is the predicted sales revenue of swimwear given 25 days of an outside temperature of over 80º Fahrenheit during the month?

$1,622.00

$2,320.00

$2,351.00

$2,578.00

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
